Ben Jackson 7244e9c2f5 [LLDB] libcxx summary formatters for std::string_view ...

When printing a std::string_view, print the referenced string as the
summary. Support string_view, u32string_view, u16string_view and
wstring_view, as we do for std::string and friends.

This is based on the existing fomratter for std::string, and just
extracts the data and length members, pushing them through the existing
string formatter.

In testing this, a "FIXME" was corrected for printing of non-ASCII empty
values. Previously, the "u", 'U" etc. prefixes were not printed for
basic_string<> types that were not char. This is trivial to resolve by
printing the prefix before the "".
